* Increase in number of interruption due to heavy rain/cyclone during June/July 2005
It can be seen from the above table that the failure rate of distribution transformers,
though reducing, is still high. The interruptions per feeder per month are low.
Transmission and Distribution Losses
The combined T&D losses have shown reduction in the year 2003 from the previous
level but there seems to be no further improvement in next year. Considering that the
transmission loss is of the order of 4.4 per cent, the level of distribution loss works out
to 26.2 per cent, which is high. The data for the year 2005-06 is not available. Hence,
the present level of losses is not known. However, it has been indicated in the FRP
that distribution losses would be reduced progressively as under:
2005 2006 2007 2008 2009 2010
-06 -07 -08 -09 -10 -11
Distribution loss (%) 26.46 22.4 19.11 16.51 15.62 15.08
Now that the JGY scheme is almost completed, accurate consumption of agricultural
consumers can be worked out from the energy meters installed on feeder panels. It is
likely that it may reveal that actual consumption in the agricultural sector is less than
that assumed and that the distribution losses are higher than the level indicated above.
Therefore DTC-wise energy accounting will have to be done to target high loss areas
for concentrating effort for reducing losses in future. The programme of fixing energy
meters on DTCs needs to be expedited.
